At what time between 9 and 10 o'clock will the hands of a watch be together?

A (49 + 3/11) min past 11

B (49 +1/11) min past 9

C (45 +1/11) min past 9

D (45 +7/11) min past 11

Correct Answer: Option B

To be together between 9 and 10 o'clock, the minute hand has to gain 45 min. spaces.
55 min. spaces gained in 60 min.

45 min. spaces are gained in \(\frac{60}{55}\times45\) min or \(49\frac1{11}\) min
